Is restaurant.com now using variable prices for the certificates? I thought it was always like $10 for a $25, $20 for a $50 cert, etc. Now I see all kinds of prices for the $25 denomination, $10, $12.50, $15, etc. Also a lot of the $50 and $100 denominations are no longer available. It looks like their software is running this like the airlines, keep changing the price as the seats sell or when special discounts are offered.
